I suggest you don't. It is more wrong than right. Example:

% irb
 >> x = []
=> []
 >> ObjectSpace.each_object(Module) { |k| x << k if k.name =~ /^[a-z]/ }
=> 341
 >> x
=> [fatal]

Using module_eval is dumb too. Use this instead:

full_name.split(/::/).inject(Object) { |klass, name| klass.const_get  
name }
